Xcode构建错误链接器命令失败，退出代码为1（使用-v查看调用）

Question

I am opening up an existing project in xcode 7.2. I'm getting the following error:

Library not found for -lBolts

Linker command failed with exit code 1 (use -v to see invocation)

Answer 1

Look for Bolts here;

Your best approach is probably to use cocopods to install it. See the bottom of the page for installation info.

(Your error results because the library that your app needs is not available to xcode.)
